ABSTRACT
Low reduction ratios and high wear rates are the two characteristics monh" associated with conventional roll crushers. Because of this, roll crushers are not often considered Jor use in mineral processing circuits, attd many of their advantages are being largely overlooked. This paper describes a novel roll crusher that has been developed ipt order to address these to as the NCRC (Non-Cylindrical Roll Crusher), the new crusher incorporates two prised qf an alternating arrangement of platte attd convex or concave ******@wes. These unique roll prqfiles improve the angle qf nip, enabling the NCRC to achieve higher reduction ratios than conventional roll crushers. Tests with a model prototype have indicated thar evell fi)r very hard ores, reduction ratios exceeding lO:l can be attained. In addition, since minution process in the bines the actions of roll arM jaw crushers there is a possibili O' that the new profiles may lead to reduced roll wear rates. © 2001 Elsevier Science Ltd.
